摘　　要：为探究千米深井摩擦提升过程中制动动态特性,通过动力学分析建立制动器的安全制动力矩和工作制动力矩分别与系统变位质量、运动方程之间的数学模型。以JKMD-5×4(Ⅲ)型落地式多绳摩擦式提升机为研究对象,得到了不同工况下摩擦提升系统制动力矩随时间的动态变化曲线,为提升机制动系统选型设计提供依据。In order to explore the dynamic characteristics of the braking torque during frictional hoisting of the hoist used in deep shaft over 1 000 m, after dynamic analysis, the paper established the mathematical model between safety braking toque and working braking torque with equivalent mass of system and motion equation respectively. In addition, taking JKMD-5×4（Ⅲ） fl oored multi-rope friction hoist as the study object, the paper obtained the dynamic variation curve of the braking torque of the friction hoisting system with time in various operation modes, which offered reference for the sizing and design of the hoist braking system.
